UFO Sightings?

Well, if there really is no minimum thickness, then I'm fine with running 
the same rotors.  I guess I ran a little too long on the pads, as the 
annular ring of which you speak, located on the outer diameter of the rotor, 
is more or less gone.  I finally noticed the metal to metal sound yesterday 
while driving with the window open, otherwise, wasn't too loud.  Luckily, 
only a portion of  the pad backing made contact...the pad obviously didn't 
wear completely true.  One corner is slightly more worn than another.

If I find that the rotor needs replacing, at least now I know where to go.  
I'm just not ready to shell out a ton of money on rotors for a car with such 
high mileage.
